For processes involving structure functions and/or fragmenation functions,but not jets,arguments are given that,at not too small values of a proper kinematic variable,there is a part dominating the NNLO QCD corrections.The arguments are tested against complete calculations. The case of jets is briefly discussed. A case when these arguments may not be useful is also mentioned.
